Hey, I'm a brand new BB user! My BB came with a 1gb memory card but I'd like to upload all my music so need a larger card. I know I have to check the O/S to see what size my bb can support, and I know I check this on the 3rd line in options>about but is it the first set of numbers v4.6.1.133 or these >> (Platform 4.2.0.85). It's a curve 8900

Sorry if it's a stupid question, but this is all very new to me!!! Thanks to anyone who can help!
